Commentary:

This is a very enlightening article on how sugar leads to cavities. This mechanism is a little surprising. Decay occurs on teeth when the bacteria that line the teeth feed on sugar in the mouth, creating forms of acid that destroy tooth enamel. When you eat something sweet, the sugar in the treat is converted to acid by the bacteria in about 20 seconds and then lasts for roughly 30 minutes. So, surprisingly, the worst thing you can so is snack on sweets or sip on a sugary drink all day. You’d be healthier eating your sugar in short spurts than continually throughout the day!
